Re: strict

[dimmesdale]

you have to say my $opt_u, or the compiler will spit an error -- or you could say (assuming main package) $MAIN::opt_u and be gone with it.

This is because use strict requires you're variables to be declared -- or, as I think on it, you could say use vars qw/$opt_u ... others here.../; (hey, TMTOWTDI :)

May I suggest, however, that (I assume you're using a GetOpt:: module here) you don't let the GetOpt module assign $opt_<whatever>, but instead pass it a hash reference. This way you can say $opts->{<whatever>} and be done with it.

I agree that you're probably better off just getting your opts out of the hash, but to clear up your initial comment, I'm pretty sure the (official/newest) way to declare it would be...

our $opt_u;

This makes it global and is necessary since you want to be accessing the same variable that Getopt is using.

Update: Just read the comment by dws below. I was thinking of Getopt::Std. I have no idea how GetOpt works.
